Low volatility doesn't mean stable. Bitcoin has experienced periods of low volatility many times, however this doesn't mean bitcoin is stable, not even close. We all know it doesn't take much for bitcoin to explode, either up or down. That's absolutely still in the cards, I mean everyone is waiting for the next bull run and some people are waiting for a big crash.
It's like saying, this bomb is stable because it hasn't exploded yet.
Bitcoin will never be stable unless it was being centralized because government has a power to control its value when it happen.since bitcoin was remain decentralised its value will not be stable, instead it is volatile where most people like to bitcoin.
